We (and Dr. Fitzharris) enter these sensitive parts via a bit of junk preserved at the Royal College of Surgeons: the severed penis which long ago inhabited, along with the bacterium Neisseria gonorrhoeae, the trousers of a highway robber named George Robertson.

Neither bacterium nor reader will be surprised to discover that when Robertson and a couple of other hard men knocked down James Holland in Mansfield Street to dispossess him of his hat and his wig, the pestilential thief resided at “a bawdy-house” (per the evidence of his perfunctory trial).

We don’t know the ins and outs of what this specimen got up to when Robertson had his liberty — only that its condition was so obvious that it interested the doctors. With nary a care for patient privacy, the Ordinary of Newgate emitted to the public that Robertson felt “so ill with the foul Disease, as not to be able to walk, and wished himself dead, because he had no Money or Friend to put him in the Hospital.”*

Agony though it might have been to our dissolute footpad, such cocks excited the physicians.

Dr. Fitzharris directs our attention to A Treatise on the Venereal Disease, by Robertson’s contemporary, the surgeon John Hunter. Hunter might well have fondled this very todger in his own day; as we learn from this turgid treatise, he and his colleagues found in the engorged members of the hung a penetrating scientific tool. The eightfold execution in the spring of 1753 that Hunter references below might be a previous Tyburn hanging date, of February 12, 1753. (That hanging included Robertson’s accomplice John Briant or Bryant: no word on the condition of John Briant’s John Thomas.)

Till about the year 1753 it was generally supposed, that the matter from the urethra in a gonorrhoea arose from an ulcer or ulcers in that passage; but from observation it was then proved that this was not the cafe. It may not be improper to give here a short history of the discovery of matter being formed by inflammation without ulceration.

In the winter 1749, a child was brought into the room used for dissection, in Covent Garden, on opening of whose thorax a large quantity of pus was found loose in the cavity, with the surface of the lungs and the pleura furred over with a more solid substance similar to coagulable lymph. On removing this from those surfaces they were found intire. This appearance being new to Dr. Hunter, he sent to Mr. Samuel Sharp, desiring his attendance, and to him it also appeared new. Mr. Sharp afterwards in the year 1750, published his Critical Enquiry, in which he introduced this fact, “That matter may be formed without a breach of substance;” not mentioning whence he had derived this notion. It was ever after taught by Dr. Hunter in his lectures ; we however find writers adopting it without quoting either Mr. Sharp or Dr. Hunter. So much being known, I was anxious to examine whether the matter in a gonorrhoea was formed in the same way. In the spring of 1753 there was an execution of eight men, two of whom I knew had at that time very severe gonorrhoeas. Their bodies being procured for this particular purpose, we were very accurate in our examination, but found no ulceration, the two urethras appeared merely a little blood-shot, especially near the glans. This being another new fact ascertained, it could not escape Mr. Gataker, ever attentive to his emolument, who was then attending Dr. Hunter’s lectures, and also practising dissection under me. He published, soon after in 1754, a treatise on this disease, and explained fully, that the matter in a gonorrhoea did not arise from an ulcer, without mentioning how he acquired this knowledge; and it has ever since been adopted in publications on this subject. Since the period mentioned above, I have constantly paid particular attention to this circumstance, and have opened the urethra of many who at the time of their death had a gonorrhoea, yet have never found a fore in any ; but always observed that the urethra near the glans was more blood-shot than usual, and that the lacunae were often filled with matter.

* As usual, the Ordinary plied the condemned while they languished in Newgate. However, he broke with his usual practice and did not make the trip to Tyburn for this triple execution, “because as they all three died Roman Catholicks, I did not choose to attend, to give them the Opportunity of turning their Backs upon me, as a Protestant Minister, which I knew they must do if I did.”
